Your case reminded me of my personal case, when I was new to Perl programming. I never used to use any external modules in my code. Just because I was Not aware of CPAN and I wanted to develop everything myself (I realized later that it is Not a practical thing to do, you enjoy but your Boss suffers because of delay of submitting assignment).
If you don't use any module then the code automatically becomes lengthy, it would surely cross 100 lines. To give you a suggestion, please write a code to convert a text file from one format to other format (e.g. one XML dtd to other XML dtd). This assignment would involves pure regular expressions and would Not need any external module
I have written RTF to text converter without using any external modules, it is 1147 loc, I took lot of time to understand RTF format and develope the code (After writing the code I came to know that there is something similar available in CPAN :-))
